Since 1998, Shaanxi Roadbest Road Machinery Co., Ltd. has been committed to the design, manufacturing, and global supply of asphalt mixing plants — critical equipment for modern road construction. Over more than two decades, Roadbest has continually innovated to meet changing market demands, progressing from mobile drum-type mixers to highly modular, efficient, and user-friendly plants designed for large-scale infrastructure projects worldwide.
1. The Beginning: YLB Series Mobile Continuous Asphalt Mixing Plant
Roadbest’s journey in asphalt mixing equipment began with the YLB Series Mobile Continuous Asphalt Mixing Plant. This early model was based on a continuous drum mixing design, where aggregates and bitumen are heated and mixed continuously as they pass through a rotating drum. The design prioritized simplicity, transportability, and operational efficiency — making it particularly suitable for Level 3–4 roads, highway maintenance, and county or township projects.
Key traits of YLB Series include:
Continuous mixing for a steady output of asphalt mixture.
Compact, modular structure, allowing the unit to tow easily and relocate between sites.
Low manufacturing and operating costs, with fuel choice flexibility.
Production rates from about 20 to 120 tph, depending on configuration.
This series laid the foundation for Roadbest’s reputation for reliable, cost-effective asphalt mixing solutions — especially in markets where mobility and quick setup are critical.
2. Elevating Performance: LB Series Traditional Batch Asphalt Mixing Plants
As project scope and performance requirements expanded, Roadbest introduced the LB Series Batch Asphalt Mixing Plant — a more versatile, batch-type stationary plant. Unlike the continuous design of the YLB, the LB Series adopted a batch mixing approach,weighing and mixing aggregates, fillers, and bitumen precisely before discharge. This approach improves asphalt consistency and formula accuracy.
Notable features of LB Series plants include:
Batch mixing technology for higher accuracy and consistency in asphalt formulas.
Advanced automation and PLC controls for improved process control and reduced manual intervention.
Production range from about 40 to 320 tph, suitable for larger infrastructure needs.
Modular construction — making transportation and installation easier compared to older fixed systems.
Over years of iterations, the LB Series became the workhorse for traditional asphalt production, supporting high-standard highways, municipal roads, and expressway projects around the world.
3. Modern Innovation: JLB Series Container-Type Asphalt Mixing Plant (2024)
In 2024, Roadbest launched the JLB Series Container-Type Asphalt Mixing Plant, representing the latest evolution of asphalt plant design. The JLB Series is a modular, highly integrated batch plant, designed for fast deployment, low cost, and environmental compliance.
Instead of assembling disparate components on site, the JLB Series adopts a containerized configuration, where core systems (cold feed, drying drum, weighing and mixing tower, control cabinets, silos, and dust collection) are pre-integrated into standardized modules. This innovation dramatically reduces installation time, site labor, and foundation costs, providing a “plug-and-play” experience for end users.
Rapid setup: deploy on site in days, not weeks.
Lower total cost: reduced civil work and labor expenses.
Portable and relocatable: ideal for phased or remote construction projects.
Environmentally friendly: integrated dust and fume control systems.
Flexible capacity: suitable for city roads, highways, and expressways.
The JLB Series combines batch plant precision with modular engineering efficiency, meeting modern infrastructure demands for speed, quality, and sustainability.
4. Looking Forward
From the early YLB continuous mixers to the traditional LB batch plants, and now to the containerized JLB solution, Shaanxi Roadbest’s evolution reflects industry trends toward modular, efficient, and eco-friendly asphalt production. Each generation of equipment built upon the last, responding to broader project scales, automation expectations, and global environmental standards.
As Roadbest continues to iterate — integrating smarter controls, advanced emission systems, and production flexibility — the company’s 25+ years of asphalt plant innovation is poised to support ever more ambitious road infrastructures worldwide.
